[ Upstream commit f5ce071462 ]
When add_addr_timeout was set to 0, this caused the ADD_ADDR to be
retransmitted immediately, which looks like a buggy behaviour. Instead,
interpret 0 as "no retransmissions needed".
The documentation is updated to explicitly state that setting the timeout
to 0 disables retransmission.
